Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a telescopic stick for self-defense use, baton, walking stick, or when walking a dog.

[0002]

[Prior Art]

 Conventionally, as an baton or a stick for self-defense, which is excellent in portability, an antenna-type telescopic rod body has been provided.

[0003]

[Problems to be solved by the device]

 However, with the conventional antenna type telescopic rod, pressing the rod tip in the extended state easily inserts the rod tip into the inside, so that it can be used for contacting a rushing object or supporting the body. There was the inconvenience that the original purpose could not be achieved. For this reason, after the rod was extended, a stopper device was attached to the joint of each pipe, but it was troublesome to attach and detach the stopper device each time, and in the event of an emergency It was difficult to operate.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a holder pipe 1 that constitutes a handle portion, a relay pipe 2 that is slidably fitted in the holder pipe 1 in the axial direction, and an axial slide in the relay pipe 2. In a single rod that is fully expandable and contractable and is composed of a tip pipe 3 that freely fits, the pipes are automatically locked in the extended state by extending the pipes at the joints of the pipes 1, 2 and 3. Stoppers 13 and 18 are provided, and a releasing portion 26 for releasing the lock between the tip pipe 3 and the relay pipe 2 by manual operation is provided on the tip pipe 3, and the tip pipe 3 is inserted into the relay pipe 2 and slides. It is characterized in that it is provided with a releasing portion for automatically releasing the lock between the relay pipe 2 and the holder pipe 1 by the insertion.

[0005]

[Action]

 The relay pipe 2 and the tip pipe 3 are fitted and stored in the holder pipe 1 when carrying, and the tip end pipe 3 is gripped and pulled out when used, so that the tip end pipe 3 and the relay pipe 2 are sequentially slid and extended. Then, the entire rod is extended. When in the extended state, the stoppers 13 and 18 provided near the joints of the pipes 1, 2 and 3 are automatically operated to lock the joints, so that both the tip pipe 3 and the relay pipe 2 are holder pipes. It is in a state where it cannot be inserted and moved toward the inside of 1. Therefore, it is possible to prevent the rod body from shrinking even if an axial load is applied to the tip portion. Further, since the stoppers 13 and 18 have a structure which operates automatically only by extending the pipes 1, 2 and 3, the user is relieved from the trouble of locking the joint portion himself.

When the stick is stored, the lock of the stopper 18 between the tip pipe 3 and the relay pipe 2 is released by a simple operation of pulling the releasing portion 26 attached to the tip pipe 3 toward the tip end of the tip pipe 3, It is possible to insert and move the above into the relay pipe 2. Then, when the tip pipe 3 is inserted and moved into the relay pipe 2, the releasing portion 12a provided in the relay pipe 2 engages with the releasing portion 8b formed at the base end portion of the tip pipe to operate. The lock of the stopper 13 between the relay pipe 2 and the holder pipe 1 is automatically released, and the relay pipe 2 can be inserted and moved into the holder pipe 1. Therefore, the user can store and slide the pipes 1, 2 and 3 simply and quickly by only manually operating the releasing portion 26 of the tip pipe 3.

【Example】

 The embodiment shown in the drawings will be described in detail below. A relay pipe 2 of the same material is fitted to a holder pipe 1 which is a hollow cylindrical pipe made of a metal such as a light alloy or a hard plastic such as FRP so as to be axially movable back and forth. Further, a front end pipe 3 made of the same material is fitted in the relay pipe 2 so as to be axially movable back and forth. Stoppers 5 and 5 are internally provided on the inner wall of the open end of the holder pipe 1, and a circular tubular guide member 6 is fitted on the outer side of the proximal end of the relay pipe 2, and the relay pipe 2 is pulled out from the inside of the holder pipe 1. At this time, the peripheral edge 6a of the guide member contacts the stoppers 5 and 5 to prevent the stopper member 5 from being pulled out. Similarly, stoppers 7, 7 are also provided on the inner wall of the open end of the relay pipe 2, and the peripheral edge 8a of the guide member 8 fitted in the base end portion of the tip pipe 3 contacts the stoppers 7, 7 to prevent removal. ..

Inside the base end of the relay pipe 2, a mounting member 11 having an inclined surface 10 having a V-shaped cross section is internally provided, and a leaf spring 12 is attached to the mounting member 11 in a V-shape. It is attached so as to bend along the inclined surface 10. A lock member 13 having the function of a stopper is penetrated and fixed to the leaf spring 12, and the lock member 13 is constantly pressed upward by the action of the bent leaf spring 12. A hole 14 is formed in a portion of the peripheral wall of the relay pipe 2 that abuts the lock member 13 so that the lock member 13 projects outward when the relay pipe 2 is pulled out from the holder pipe 1. Therefore, when the relay pipe 2 is extended, the lock member 13 automatically protrudes, and even if a force for pushing the relay pipe 2 back into the holder pipe 1 is applied thereafter, the lock member 13 is locked by the stopper 5. Will not be stored and moved.

Inside the tip pipe 3, there is a lever 19 having one end forming an engaging portion 17 and the other end forming a locking portion 18 having a stopper function. It is pivotally supported by the lever center 19a so as to be directed to the side. A leaf spring 21 having a downward pressing force is attached to the lower side of the lock portion 18-side lever. As a reaction of the leaf spring 21 contacting the inner wall of the tip pipe 3, the lock portion 18-side lever always moves upward. Being pressed against. A hole 22 is formed in a portion of the peripheral wall of the tip pipe 3 that abuts on the lock portion 18 so that the lock portion 18 pressed by the leaf spring 21 when the tip pipe 3 is pulled out from the relay pipe 2 projects outward. Has been drilled. For this reason, the lock portion 18 automatically protrudes at the same time when the tip pipe 3 is extended, and even if a force for pushing the tip pipe 3 back into the relay pipe 2 is applied thereafter, the lock portion 18 is locked by the stopper 7 and is stored. It will not be moved.

A slit pipe 25 is fitted and fixed to the opening side of the tip pipe 3, and an engaging member 26 having a shape as shown in FIG. 4 is fitted to the peripheral wall of the slit pipe 25 so as to be axially movable back and forth. ing. A ring 27 is externally fitted and fixed to the opening end of the slit pipe 25, and a cap-shaped tip 28 is screwed from the opening end of the slit pipe 25. The engagement member 26 is connected to the ring 27 via a coil spring 29 that winds around the slit pipe 25. The coil spring 29 always exerts a pressing force toward the tip pipe 3, so that the engaging member 26 abuts on the tip pipe edge 3a and stops.

An elongated hole 30 is formed in a portion of the peripheral wall of the slit pipe 25 that abuts the lever engaging portion 17, and a constricted portion 26 a of the engaging member 26 projects from the elongated hole 30 toward the tip pipe 3. ing. The constricted portion 26a is shaped so as to match the degree of bending of the lever engaging portion 17, and the lever engaging portion 17 is always on the constricted portion 26a. With this structure, when the extension pipes 1, 2 and 3 in the locked state are stored again, if the engaging member 26 is moved in the direction of the gripping tip tool 28, as shown in FIG. The engaging member 26, which moves to, acts to push up the lever engaging portion 17 on the constricted portion 26a, and the lever engaging portion 17 tilts upward about the shaft 19a, so that it is integrally configured. The lock portion 18 at the other end of the lever tilts downward about the shaft 19a, and as a result, the lock between the tip pipe 3 and the relay pipe 2 is released.

On the rear side of the guide member 8 fitted into the base end portion of the tip pipe 3, an inclined surface 8b having a V-shaped cross section having a function of a release portion is formed, and the tip end where the lock is released. When the pipe 3 is housed and slid into the relay pipe 2, the leaf spring tip portion 12a having a function of a release portion penetrating the lock member 13 and extending forward, has a V-shaped inclination on the rear side of the guide member 32. It comes into contact with the surface 8b and is pushed down. As the guide member 8 moves backward, the degree of bending of the leaf spring 12 as a whole increases, and the lock member 13 fixed to the leaf spring 12 also descends downward, resulting in the lock between the relay pipe 2 and the holder pipe 1. Then, the relay pipe 2 and the tip pipe 3 can be accommodated in the holder pipe 1 and slide. In this case, it is desirable that the tip end portion 12a of the leaf spring has a flat triangular shape (not shown) so that the leaf spring tip portion 12a is easily engaged with the V-shaped inclined surface 8b.

Since the front surfaces of the lock member 13 and the lock portion 18 are both inclined surfaces 13a 1 and 18b which are greatly inclined, the lock member inclined surface 13a acts on the stopper 5 when the rod body in the stored state is extended. Even if the lock portion inclined surface 18a abuts on the stopper 7, the pulling force is applied to the lock member 13 and the lock portion 18 so that the lock member 13 and the lock portion 18 are lowered without resistance.

A ring-shaped collar 35 is rotatably attached to the handle portion of the holder pipe 1, and is axially supported by the peripheral wall of the holder pipe 1 at the central portion. The collar 35 can be used as a non-slip handle or a shield for protection when the collar 35 is rotated and raised when contacting a rushing object with the tip of the stick or supporting the body. .. A cap 37 having a hole 36 in the center is fitted in the base end portion of the holder pipe 1, and a string 38 is inserted in the hole 36. The material, shape, weight and the like of the present invention can be arbitrarily determined according to the user group, the application, etc. in addition to the above-mentioned embodiment.
